change special characters

i need the users to type a keyword in a 'google like' seachbar (then click a button named'search').  after clicking, the keyworld would replace all special this characters ## (or any other character you suggest) in this scripts.

<li><a class="current" href="http://www.digg.com=+##" onClick="return handlelink(this)">Google</a></li>
<li><a href="http://www.reddit.com" onClick=+##"return handlelink(this)">Yahoo</a></li>

<iframe name="cwindow" style="border:2px solid black" width=479 height=219 src="http://www.digg.com+##" target="cwindow"></iframe>
<iframe name="cwindow" style="border:2px solid black" width=479 height=219 src="http://www.reddit.com+##" target="cwindow"></iframe>

i'm a newbie to javascript.it would be useful (very very much) if anybody can write the entire script.thank you.

Not sure what you want to do. Replace is done using the replace function.
<script type=text/javascript>
var rx=/\#\#/g
var s="http://www.digg.com=+##"
var search="some string"
alert(s.replace(rx, search));

But based on the code you gave, try this: http://www.sendspace.com/file/5yjlrj multiSiteSearch.htm
Do you want the '##' in <li><a class="current" href="http://www.digg.com=+##" onClick="return handlelink(this)">Google</a></li>
to be replaced with whatever you typed in the searchbar?


Whatever you typed in the searchbar to be replace with '#'?

the first one. that is,  ## in <li><a class="current" href="http://www.digg.com=+##" onClick="return handlelink(this)">Google</a></li>
will be replaced with whatever users typed in the searchbar.

the multisitesearch is exactly what i looking for, but i have huge set of iframes ( in many saiz and position in webpage) that i have already designed. so i'm looking for just the onclick (searchbar) script. something like the replace function that callrs gave ( but not working). i stress again that the multisite search is exactly what i was looking (perfectly) for but i already did the webpage layout with iframes so i just need search bar replace function.

Hover over the Google & Yahoo links & read the full text in the status bar. Then click "Replace", then hover over the links again to see that they've changed.

i have a script like this (script 1) .i'm looking for a script like this but would do exactly what multisite search would do. the user input would replace/add/submit (any one of these) to other search engin in iframe.(script2-which already inplace in my site)


<form action="http://www.mysite.com
" method="replace">
<h6 align="center">
<input type="hidden" name="p" value="1" />
<input type="hidden" name="lang" value="en" />
<input type="hidden" name="include" value="" />
<input type="hidden" name="exclude" value="" />
<input type="hidden" name="penalty" value="0" />
<font color="#FFFFFF"> Search for:</font>
<input type="text" name="q" />
<input type="submit" value="Search" name="submit" />


<li><a class="current" href="http://www.google.com/search?hl=en&q=" onClick="return handlelink(this)">Google</a></li>
<li><a href="http://http://search.yahoo.com/search?p=" onClick="return handlelink(this)">Yahoo</a></li>
<li><a href="http://search.msn.com.sg:80/results.aspx?q=" onClick="return handlelink(this)">MSN</a></li>

Thanks. Here's the code for reference:

<!-- Mulit site search

<script type="text/javascript">
function handlelink(obj, frameid){
var search, url, addon="";
search=document.forms.form1.In1.value.split(" ");
for (i=0; i<search.length-1; i++) addon=addon+search[i]+"+"
return false;

<body onload='document.forms.form1.In1.focus()'>
<li><a id=link1 class="current" href="http://www.google.com/search?q=" onClick="return handlelink(this,'cwindow1')">Google</a></li>
<li><a id=link2 href="http://search.yahoo.com/search?p=" onClick="return handlelink(this,'cwindow2')">Yahoo</a></li>
<form name=form1 onsubmit="handlelink(document.getElementById('link1'),'cwindow1'); return handlelink(document.getElementById('link2'),'cwindow2')">
Search query: <input name=In1 value="apples oranges">
<input type=submit name="Search" >
